Question

Rickey has fraction 7 over 8 of a cup of cereal in a bowl. He then gave two fraction 1 over 4 cups of cereal from his bowl to his little sister. Which of the following best explains the amount of cereal left in Rickey's bowl? fraction 3 over 8, because fraction 7 over 8 minus 2 times fraction 1 over 4 equals fraction 7 over 8 minus fraction 2 over 4 fraction 3 over 8, because fraction 7 over 8 minus 2 times fraction 1 over 4 equals fraction 7 over 8 minus fraction 3 over 4 fraction 1 over 8, because fraction 7 over 8 minus 2 times fraction 1 over 4 equals fraction 7 over 8 minus fraction 2 over 4 fraction 1 over 8, because fraction 7 over 8 minus 2 times fraction 1 over 4 equals fraction 7 over 8 minus fraction 3 over 4

Answer 1

Fraction 3 over 8, because fraction 7 over 8 minus 2 times fraction 1 over 4 equals fraction 7 over 8 minus fraction 2 over 4.

Explanation:

Rickey has
`(7)/(8)` of a cup of cereal in a bowl.

He then gave two
`(1)/(4)` or
`2* (1)/(4)` or
`(2)/(4)` cups of cereal from his bowl to his little sister.

Amount of cereal left in Rickey's bowl =
`(7)/(8)- (2)/(4)`

=
`(7-4)/(8)=(3)/(8)`

So, the answer is -

Fraction 3 over 8, because fraction 7 over 8 minus 2 times fraction 1 over 4 equals fraction 7 over 8 minus fraction 2 over 4.
